The present investigation entitled, “Evaluation of botanicals and synthetic insecticides against major pests of brinjal”, was conducted during kharif 2017-18 on the field of Department of Entomology Dr. Panjabrao Deshmukh Krishi Vidhyapeeth, Akola. The effects of botanicals along with synthetic insecticides were assessed against pests of brinjal to find out the cost effective treatment. The experiment was laid out in randomized block design (RBD) with twelve treatments replicated thrice. Total five sprays of the above treatments were done at an interval of 15 days commencing first application at 30 days after transplanting. The treatment Thiamethoxam 25 WG@ 0.4 g/L followed by Imidacloprid 17.8 SL @ 0.25 ml/L, Triazophos 40 EC @ 2 ml/Land NSE (Neem Seed Extract) @7% were found significantly effective in recording lower population of sucking pests i.e. leafhopper, whitefly and mites.
